(T0/ALL "WHOM IT MAY CONCERN:

Be it known that I, PETER BROADBOOKS, of Batavia, in the county ofGenesee, and State of New York, have invented a new and usefulImprovement in- Nippers or Wire- Cutting Pincers; and 'I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 is a side view of my improveduippers.

Figure 2 is a detached view of the collar to fasten the nppers together.

Figure 3 is a detached viewof the parts composing the nippers.

Similar letters of reference indicate like parts.

This invention consists in an improved construction of cutting pincers,pliers, or I1ippers,-especially adaptedk to cutting wire, but equallyapplicable to all similar uses wherein metal or hard and toughsubstances require great power to sever them easily. This improvementconsists in-an entirely new construction and arrangement of the partswhich form a pair of pincers, three pieces being employed instead oftwo, as usual, and are secured and .jointed together by means of acollar-aroundV the head or jaws of the pincers, instead of being rivetedin theordinary manner.

The object of this device is to obtain great leverage power in thecutting jaws, and the reacting movement of a spring to open the jaws.

A rectangular metal collar, a, is fitted around the heads c c of the twooutside metal handles or legs b b', and between the legs b b splaced asteel spring, d, the head c1 of which is also enclosed in the collar a.Upon .the heads of the leg b and the spring d are` welded, or fastenedwith rivets or screws, steel jaws or cutting plates e e. The head of thespring 0l is fitted to Work in the head of the leg b by Vaknuckle-joint, of which g is the knuckle on the'spring, and 7L thesocket in which it tits onthe. leg b. The other end of the spring dbears against .the inside of the leg b, and teds to open the jaws e e. Acam may be employed in place of the knuckle. It will be seen that bythisconnection of the legs and spring with each other by means of the collara., the leg b acts as a powerful lever upon the spring c, which, withits short arm or head, draws the cutting jaws e e together upon wife orother substanceto be cut between them, while the spring c will throw thejaws open the instantthepressure of the hand on the legs is removed.

Having described my invention, I claim as new, and desire to secure byLetters Patent-4 The legs b b/and spring d, secured together by means ofthe rectangular collar a, fitting over and working upon the heads c e'ofthe legs b b and spring d, the latter connected to the leg b by means ofthe knuckle- Vjoint, composed of the knuckle g and socket h, allconstructed and arranged substantially as described, for the purposespecified.

PETER BROADBOOKS.
